The island was called by various names by its native people, the TaínoAmerindians. No known Taíno texts survive, hence, historical evidence for those names comes to us through three historians: the Italian Pietro Martyr d‘Anghiera, and the Spaniards Bartolomé de las Casas and Gonzalo Fernández de Oviedo. Fernández de Oviedo and de las Casas both recorded that the island was called Haiti ("Mountainous Land") by the Taíno. D'Anghiera added another name, Quizqueia (supposedly "Mother of all Lands"), but later research shows that the word does not seem to derive from the original Arawak Taíno language.[3] (Quisqueya is today mostly used in the Dominican Republic.) Although the Taínos' use of Haiti is verified, and the name was used by all three historians, evidence suggests that it probably was not the Taíno name of the whole island, but only for a region (now known as Los Haitises) in the northeastern section of the present-day Dominican Republic.

When Columbus took possession of the island in 1492, he named it Insula Hispana in Latin[7] and La Isla Española in Spanish,[8] with both meaning "the Spanish island". De las Casas shortened the name to "Española", and when d‘Anghiera detailed his account of the island in Latin, he rendered its name as Hispaniola.[8] In the oldest documented map of the island, created by Andrés de Morales, Los Haitises is labeled Montes de Haití ("Haiti Mountains"), and de las Casas apparently named the whole island Haiti on the basis of that particular region,[4] as d'Anghiera states that the name of one part was given to the whole island.[3]

Due to Taíno, Spanish and French influences on the island, historically the whole island was often referred to as Haiti,Hayti,Santo Domingo,St. Domingue, or San Domingo. The colonial terms Saint-Domingue and Santo Domingo are sometimes still applied to the whole island, though these names refer, respectively, to the colonies that became Haiti and the Dominican Republic.[9] Since Anghiera's literary work was translated into English and French soon after being written, the name "Hispaniola" became the most frequently used term in English-speaking countries for the island in scientific and cartographic works. In 1918, the United States occupation government, led by Harry Shepard Knapp, obliged the use of the name Hispaniola on the island, and recommended the use of that name to the National Geographic Society.[10]

The name Haïti was adopted by Haitian revolutionary Jean-Jacques Dessalines in 1804, as the official name of independent Saint-Domingue, as a tribute to the Amerindian predecessors. It was also adopted as the official name of independent Santo Domingo, as the Republic of Spanish Haiti, a state that existed from November 1821 until its annexation by Haiti in February 1822.[11][12]

Christopher Columbus inadvertently landed on the island during his first voyage across the Atlantic in 1492, where his flagship, the Santa Maria, sank after running aground on December 25. A contingent of men were left at an outpost christened La Navidad, on the north coast of present-day Haiti. On his return the following year,[13] following the destruction of La Navidad by the local population, Columbus quickly established a second compound farther east in present-day Dominican Republic, La Isabela.

The island was inhabited by the Taíno, one of the indigenous Arawak peoples. The Taino were at first tolerant of Columbus and his crew, and helped him to construct La Navidad on what is now Môle-Saint-Nicolas, Haiti, in December 1492. European colonization of the island began in earnest the following year, when 1,300 men arrived from Spain under the watch of Bartolomeo Columbus. In 1496 the town of Nueva Isabela was founded. After being destroyed by a hurricane, it was rebuilt on the opposite side of the Ozama River and called Santo Domingo. It is the oldest permanent European settlement in the Americas.

Several 16th century writers estimated the 1492 population of Hispaniola at over 1 million people.[14] Twentieth-century estimates of the figure range from 60,000 to 8,000,000, but center around the 500,000 to 1,000,000 range.[14] Harsh enslavement by Spanish colonists, as well as redirection of food supplies and labor towards the colonists, had a devastating impact on both mortality and fertility over the first quarter century.[15] Colonial administrators and Dominican and Hyeronimite priests observed that the search for gold and agrarian enslavement through the encomienda system were depressing population.[15] Demographic data from two provinces in 1514 shows a low birth rate consistent with a 3.5% annual population decline. Just 14,000 Taínos survived in 1517.[16] In 1503 the colony began to import Africanslaves, believing them more capable of performing physical labor.[citation needed]

The first documented outbreak of smallpox, previously an Eastern hemisphere disease, on Hispaniola occurred in December 1518 among enslaved African miners.[15][17] Some scholars speculate that European diseases arrived before this date, but there is no compelling evidence for an outbreak.[15] The natives had no immunity to European diseases, including smallpox.[18][19] By May 1519, as many as one-third of the remaining Taínos had died.[17]

Christopher Columbus brought sugar cane on his second voyage to the island. Molasses was the chief product. Diego Colon's plantation had 40 African slaves in 1522. By 1526, 19 mills were in operation from Azua to Santo Domingo.[20]:224

In 1574, a census taken of the Greater Antilles reported 1,000 Spaniards and 12,000 African slaves on Hispaniola.[21]

As Spain conquered new regions on the mainland of the Americas (Spanish Main), its interest in Hispaniola waned, and the colony’s population grew slowly. By the early 17th century, the island and its smaller neighbors (notably Tortuga) became regular stopping points for Caribbean pirates. In 1606, the government of Philip III ordered all inhabitants of Hispaniola to move close to Santo Domingo, to avoid interaction with pirates. Rather than secure the island, his action meant that French, English and Dutch pirates established their own bases on the abandoned north and west coasts of the island.

In 1665, French colonization of the island was officially recognized by King Louis XIV. The French colony was given the name Saint-Domingue. In the 1697 Treaty of Ryswick, Spain formally ceded the western third of the island to France.[22][23] Saint-Domingue quickly came to overshadow the east in both wealth and population. Nicknamed the "Pearl of the Antilles," it became the richest and most prosperous colony in the West Indies, with a system of human enslavement used to grow and harvest sugar cane, during a time when demand for sugar was high in Europe. Slavery kept prices low and profit was maximized at the expense of human lives. It was an important port in the Americas for goods and products flowing to and from France and Europe.

With the treaty of Peace of Basel, revolutionary France emerged as a major European power. In the second 1795 Treaty of Basel (July 22), Spain ceded the eastern two-thirds of the island of Hispaniola, later to become the Dominican Republic. French settlers had begun to colonize some areas in the Spanish side of the territory.

European colonists often died young due to tropical fevers, as well as from violent slave resistance in the late eighteenth century. When the French Revolution abolished slavery in the colonies on February 4, 1794, it was a European first,[24] and when Napoleon reimposed slavery in 1802 it led to a major upheaval by the emancipated black slaves.

Thousands of the French troops sent by Napoleon to reestablish slavery succumbed to yellow fever during the summer months, and more than half of the French army died because of disease.[25] After the French removed the surviving 7,000 troops in late 1803, the leaders of the revolution declared western Hispaniola the new nation of independent Haiti in early 1804. France continued to rule Spanish Santo Domingo. In 1805, Haitian troops of General Henri Christophe tried to conquer all of Hispaniola. They invaded Santo Domingo and sacked the towns of Santiago de los Caballeros and Moca, killing most of their residents, but news of a French fleet sailing towards Haiti forced General Christophe to return to Haiti, leaving the eastern Spanish side of the island in French hands. In 1808, following Napoleon's invasion of Spain, the criollos of Santo Domingo revolted against French rule and, with the aid of the United Kingdom (Spain's ally) returned Santo Domingo to Spanish control.

Fearing the influence of a society that had successfully fought and won against their enslavers, the United States and European powers refused to recognize Haiti, the second republic in the western hemisphere. France demanded a high payment for compensation to slaveholders who lost their property, and Haiti was saddled with unmanageable debt for decades.[26] It became one of the poorest countries in the Americas, while the Dominican Republic [26] gradually has developed into the largest economy of Central America and the Caribbean.

Hispaniola is the second-largest island in the Caribbean (after Cuba), with an area of 76,192 square kilometers (29,418 sq mi), 48,440 square kilometers (18,700 sq mi)[27] of which is under the sovereignty of the Dominican Republic occupying the eastern portion and 27,750 square kilometers (10,710 sq mi)[6] under the sovereignty of Haiti occupying the western portion.

Cuba, Hispaniola, Jamaica, and Puerto Rico are collectively known as the Greater Antilles.

The island has five major mountain ranges: The Central Range, known in the Dominican Republic as the Cordillera Central, spans the central part of the island, extending from the south coast of the Dominican Republic into northwestern Haiti, where it is known as the Massif du Nord. This mountain range boasts the highest peak in the Antilles, Pico Duarte at 3,098 meters (10,164 ft) above sea level. The Cordillera Septentrional runs parallel to the Central Range across the northern end of the Dominican Republic, extending into the Atlantic Ocean as the Samaná Peninsula. The Cordillera Central and Cordillera Septentrional are separated by the lowlands of the Cibao Valley and the Atlantic coastal plains, which extend westward into Haiti as the Plaine du Nord (Northern Plain). The lowest of the ranges is the Cordillera Oriental, in the eastern part of the country.[28]

The Sierra de Neiba rises in the southwest of the Dominican Republic, and continues northwest into Haiti, parallel to the Cordillera Central, as the Montagnes Noires, Chaîne des Matheux and the Montagnes du Trou d'Eau. The Plateau Central lies between the Massif du Nord and the Montagnes Noires, and the Plaine de l‘Artibonite lies between the Montagnes Noires and the Chaîne des Matheux, opening westward toward the Gulf of Gonâve, the largest gulf of the Antilles.[28]

The southern range begins in the southwestern most Dominican Republic as the Sierra de Bahoruco, and extends west into Haiti as the Massif de la Selle and the Massif de la Hotte, which form the mountainous spine of Haiti’s southern peninsula. Pic de la Selle is the highest peak in the southern range, the third highest peak in the Antilles and consequently the highest point in Haiti, at 2,680 meters (8,790 ft) above sea level. A depression runs parallel to the southern range, between the southern range and the Chaîne des Matheux-Sierra de Neiba. It is known as the Plaine du Cul-de-Sac in Haiti, and Haiti’s capital Port-au-Prince lies at its western end. The depression is home to a chain of salt lakes, including Lake Azuei in Haiti and Lake Enriquillo in the Dominican Republic.[28]

The island has four distinct ecoregions. The Hispaniolan moist forests ecoregion covers approximately 50% of the island, especially the northern and eastern portions, predominantly in the lowlands but extending up to 2,100 meters (6,900 ft) elevation. The Hispaniolan dry forests ecoregion occupies approximately 20% of the island, lying in the rain shadow of the mountains in the southern and western portion of the island and in the Cibao valley in the center-north of the island. The Hispaniolan pine forests occupy the mountainous 15% of the island, above 850 metres (2,790 ft) elevation. The flooded grasslands and savannas ecoregion in the south central region of the island surrounds a chain of lakes and lagoons in which the most notable include that of Lake Azuei and Trou Caïman in Haiti and the nearby Lake Enriquillo in the Dominican Republic.

In Haiti, deforestation has long been cited by scientists as a source of ecological crisis; the timber industry dates back to French colonial rule.

Haiti has seen a dramatic reduction of forests due to the excessive and increasing use of charcoal as fuel for cooking. Recent in-depth studies of satellite imagery and environmental analysis regarding forest classification conclude an accurate estimate of approximately 30% tree cover,[29] a stark decrease in the 60% forest cover in 1925. Despite recent in-depth studies, the notoriously unsubstantiated 2% forest cover estimate has been widely circulated in media and in discourse concerning the country.[30] Despite the drastic underestimation of Haiti's forest cover, the country has been significantly deforested over the last 50 years, resulting in the desertification of portions of the Haitian territory.

In the Dominican Republic the forest cover has increased. In 2003 the Dominican forest cover had been reduced to 32% of the territory, but in 2011 the trend towards reducing reverts to increase forest cover by eight percentage points to stand at nearly 40% of territory. The success of the Dominican forest growth is due to several Dominican government policies and private organizations for the purpose, and a strong educational campaign that has resulted in increased awareness on the Dominican people of the importance of forests for their welfare and in other forms of life on the island.[31]

Owing to its mountainous topography, Hispaniola’s climate shows considerable variation over short distances, and is the most varied of all the Antilles.[32]

Except in the Northern Hemisphere summer season, the predominant winds over Hispaniola are the northeast trade winds. As in Jamaica and Cuba, these winds deposit their moisture on the northern mountains, and create a distinct rain shadow on the southern coast, where some areas receive as little as 400 millimetres (16 in) of rainfall, and have semi-arid climates. Annual rainfall under 600 millimetres (24 in) also occurs on the southern coast of Haiti’s northwest peninsula and in the central Azúa region of the Plaine du Cul-de-Sac. In these regions, moreover, there is generally little rainfall outside hurricane season from August to October, and droughts are by no means uncommon when hurricanes do not come.[33]

On the northern coast, in contrast, rainfall may peak between December and February, though some rain falls in all months of the year. Annual amounts typically range from 1,700 to 2,000 millimetres (67 to 79 in) on the northern coastal lowlands;[32] there is probably much more in the Cordillera Septentrional, though no data exist.

The interior of Hispaniola, along with the southeastern coast centred around Santo Domingo, typically receives around 1,400 millimetres (55 in) per year, with a distinct wet season from May to October. Usually, this wet season has two peaks: one around May, the other around the hurricane season. In the interior highlands, rainfall is much greater, around 3,100 millimetres (120 in) per year, but with a similar pattern to that observed in the central lowlands.

As is usual for tropical islands, variations of temperature are much less marked than rainfall variations, and depend only on altitude. Lowland Hispaniola is generally oppressively hot and humid, with temperatures averaging 28 °C (82 °F). with high humidity during the daytime, and around 20 °C (68 °F) at night. At higher altitudes, temperatures fall steadily, so that frosts occur during the dry season on the highest peaks, where maxima are no higher than 18 °C (64 °F).

The Dominican Republic is a Hispanophone nation of approximately 10 million people. Spanish is spoken by all Dominicans as a primary language. Roman Catholicism is the official and dominant religion.

Haiti is a Francophone nation of roughly 10 million people. Although French is spoken as a primary language by the educated and wealthy minority, virtually the entire population speaks Haitian Creole, one of several French-derived creole languages. Roman Catholicism is the dominant religion, practiced by more than half the population, although in some cases in combination with Haitian Vodou faith. Another 25% of the populace belong to Protestant churches.[34] Haiti emerged as the first Black republic[35] in the world.

The island has the largest economy in the Greater Antilles, however most of the economic development is found in the Dominican Republic, the Dominican economy being nearly 800% larger than the Haitian economy.

The divergence between the level of economic development between Haiti and Dominican Republic makes its border the higher contrast of all western land borders and is evident that the Dominican Republic has one of the highest migration issues in the Americas.[37]

Christopher Columbus, noting "the land and trees resembled those of Spain, and that the sailors caught in their nets many fish like those of Spain...named it Espanola on Sunday, December 9th." One of the first inhabitants he came across on this island was "a girl wearing only a gold nose plug." Columbus later learned that the "land of gold was farther east." Soon the Tainos were trading pieces of gold for hawk's bells with their cacique declaring the gold came from Cibao. Traveling further east from Navidad, Columbus came across the Yaque del Norte River, which he named Rio de Oro because its "sands abound in gold dust."[38]

On Columbus' return during his second voyage he learned it was the cacique Caonabo, "lord of the mines", who had massacred his settlement at Navidad. While Columbus established a new settlement at La Isabela on Jan. 1494, he sent Alonso de Ojeda and 15 men to search for the "mines of Cibao." After a six-day journey, Ojeda came across an area "very rich in gold", in which the "Indians took gold out of a brook...and many other streams in that province." Columbus himself visited the mines of Cibao on 12 March 1494. He constructed the Fort of Santo Tomas, present day Janico, with Captain Pedro Margarit in command of 56 men.[38]:119,122–126

On 24 March 1495, Columbus with his ally Guacanagarix, embarked on a war of revenge against Caonabo, capturing him and his family while "killing many Indians and capturing others." Afterwards, "every person of fourteen years of age or upward was to pay a large hawk's bell of gold dust."[38]:149–150

Miguel Diaz and Francisco de Garay discovered large gold nuggets on the lower Haina River in 1496. These San Cristobal mines were later known as the Minas Viejas mines. Then, in 1499, the first major discovery of gold was made in the cordillera central, which led to a mining boom. By 1501, Columbus' cousin Giovanni Colombo, had discovered gold near Buenaventura, the deposits were later known as Minas Nuevas. Two major mining areas resulted, one along San Cristobal-Buenaventura, and another in Cibao within the La Vega-Cotuy-Bonao triangle, while Santiago de los Caballeros, Concepcion, and Bonao became mining towns. The gold rush of 1500–1508 ensued.[20]

Ferdinand "ordered gold from the richest mines reserved for the Crown." Thus, Ovando expropriated the gold mines of Miguel Diaz and Francisco de Garay in 1504, as pit mines became royal mines, though placers were open to private prospectors. Furthermore, Ferdinand wanted the "best Indians" working his royal mines, and kept 967 in the San Cristobal mining area supervised by salaried miners.[20]:68,71,78,125–127

Under Nicolás de Ovando y Cáceres' governorship, the Indians were made to work in the gold mines, "where they were grossly overworked, mistreated, and underfed," according to Pons. By 1503, the Spanish Crown legalized the distribution of Indians to work the mines as part of the encomienda system. According to Pons, "Once the Indians entered the mines, hunger and disease literally wiped them out." By 1508 the Indian population of about 400,000 was reduced to 60,000, and by 1514, only 26,334 remained. About half were located in the mining towns of Concepcion, Santiago, Santo Domingo, and Buenaventura. The repartimiento of 1514 accelerated emigration of the Spanish colonists, coupled with the exhaustion of the mines. In 1516, a smallpox epidemic killed an additional 8,000, of the remaining 11,000 Indians, in one month. By 1519, according to Pons, "Both the gold economy and the Indian population became extinct at the same time."[39][20]:191–192

However, writing in 1860, Courtney observed, the island is "one immense gold field", of which the early Spaniards had "scarcely began to be developed." Additionally, "The gold is still found in the Cibao regions as of old."[40] By 1919, Condit and Ross noted "the greater part of the Republic is covered by concessions granted by the government for mining minerals of diverse sorts." Besides gold, these minerals included silver, manganese, copper, magnetite, iron and nickel.[41]

Between Bonao and Maimon, Falconbridge Dominicana has been mining nickellaterites since 1971. The Cerro de Maimon copper/gold open-pit mine southeast of Maimon has been operated by Perilya since 2006. Copper is extracted from the sulfide ores, while gold and silver are extracted from both the sulfide and the oxide ores. Processing is via froth flotation and cyanidation. The ore is located in the VMS Early Cretaceous Maimon Formation. Goethite enriched with gold and silver is found in the 30 m thick oxide cap. Below that cap is a supergene zone containing pyrite, chalcopyrite, and sphalerite. Below the supergene zone is found the unaltered massive sulphide mineralization.[43]
